Problems solved by technology

There are problems in this patent: (1) High-temperature distillation affects the active ingredients of Dendrobium flowers; (2) The unilateral water extract has only one effect, and only the effect of freckle removal has been verified by animal experiments. For the precious and high-value ingredients, the comprehensive anti-aging effect has not been verified
There are problems with this technology: (1) This patent aims to develop plant-derived coloring agents to improve safety, but no safety evaluation has been carried out; (2) The patented product has not been evaluated in terms of makeup effect
There are problems with this technology: there is no research on the safety and efficacy of the obtained product, and further research is needed to apply it to skin care products
[0006] The application number is 201811309089.4 and other patents related to Trollius applied by Guangdong Dapeng Pharmaceutical Technology Co., Ltd. are all unilateral components of Trollius, and there is a problem of single efficacy. Therefore, there is no relevant functional evaluation in this series of patents

Abstract

The invention discloses a preparation method of a compound flower extract with multiple skin care effects, and belongs to the technical field of cosmetics. The preparation method comprises the following steps: (1) preparation of a calendula extract; (2) preparation of a trollflower extract; and (3) preparation of the compound flower extract. The invention discloses the preparation method of the compound flower extract with multiple skin care effects. The preparation method comprises the following steps: respectively extracting volatile active ingredients in trollflower and calendula through a distillation process to obtain colorless-to-faint yellow hydrolat with the pH value of 5-6 and weak acidity; and pretreating whole dendrobium nobile flowers with polyhydric alcohol, so that active ingredients in the dendrobium nobile flowers can dissolve out in the ultrasonic low-temperature extraction process through trollflower hydrolat and calendula hydrolat. According to the invention, a variety of extraction methods are combined, so that the different types of the active ingredients can be obtained, the active ingredients and the color of the rare flower (dendrobium nobile flowers) can be retained, and pigment-free product raw materials can be provided for the development of the cosmetics with different sensory effects.
